Some parents fear changes to state laws as FDA weighs use of CBD pharmaceuticals

COLORADO SPRINGS — Some American parents who for years have used cannabis to treat severe forms of epilepsy in their children are feeling more cautious than celebratory as U.S. regulators near a decision on whether to approve the first drug derived from the marijuana plant.

The U.S. Food and Drug Administration is expected to issue a decision by the end of the month on the drug Epidiolex, made by GW Pharmaceuticals. It’s a purified form of cannabidiol — a component of cannabis that doesn’t get users high — to treat Dravet and Lennox-Gastaut syndromes in kids. Both forms of epilepsy are rare.

Cannabidiol’s effect on a variety of health conditions is frequently touted, but there is still little evidence to back up advocates’ personal experiences. The U.S. Drug Enforcement Administration has long categorized cannabis as a Schedule I drug, a category with “no currently accepted medical use and a high potential for abuse.” That strictly limits research on potential medical uses for cannabis or the chemicals in it, including cannabidiol, or CBD.
